Wheel rim temperature detection method and device for simulating road working condition

The invention relates to a wheel rim temperature detection method and device under simulated road working conditions, and the method comprises the following steps: obtaining braking data under various working conditions, and converting the braking data into rack simulation parameters; a brake assembly, a brake drum, a rim and a tire are assembled on a brake inertia test bench, and a temperature sensor is installed; and performing a simulation test on the brake inertia test bench based on the bench simulation parameters, and detecting a temperature value of a contact position of a rim and a tire crown by using a temperature sensor. As the actual braking condition is simulated by using the brake inertia test bench according to the bench simulation parameters, the consistency of the bench simulation test and the road working condition is ensured, the bench test replaces the whole vehicle test, the test cost is reduced, the accuracy of the test data is improved, the optimal matching of different wheel assembly de
